What planet is 4 times the mass of Earth?

Density, mass and volume Although Uranus, discovered in 1781, is only four times the physical size of Earth, it is significantly more massive, weighing in at 86 septillion kilograms (just under one trillion trillion trillion).

How do you calculate surface gravity of a planet?

The acceleration that a body experiences on the surface of a planet, the gravity on surface, depends on the mass M and radius R according to a simple formula of Newton’s: a=GM/R2, in which G denotes the universal gravitational constant.

What is the acceleration due to gravity at the surface of this planet?

9.80665 m/s2
The acceleration due to gravity at the surface of Earth is represented by the letter g. It has a standard value defined as 9.80665 m/s2 (32.1740 ft/s2).

Which planet has more gravity?

Jupiter
The gravity on Jupiter is greater than the gravity on Earth because Jupiter is more massive. Although Jupiter is a great deal larger in size, its surface gravity is just 2.4 times that of the surface gravity of Earth.

What is Saturn gravity?

10.44 m/s²
Saturn/Gravity

What is the gravity near the surface of Jupiter?

As a result, Jupiter’s surface gravity (which is defined as the force of gravity at its cloud tops), is 24.79 m/s, or 2.528 g. Gravity on Saturn: Like Jupiter, Saturn is a huge gas giant that is significantly larger and more massive than Earth, but far less dense.

What is the gravity of a planet with a pherically symmetric surface?

If a planet is pherically symmetric then gravitational field on its surface is proportional to the mass and inversely proporional to a square of its radius, which gives gravity smaller by a factor of 8 (2/4^2 = 1/8).

How to calculate surface gravity of a solar planet using simple calculator?

Calculate surface gravity (Gravitational Force) of a solar planet using simple astronomy calculator. g = G × (M / R 2)

What is the Universal Gravitation Constant of Planet X?

Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is 6.674×10^-11 Nm^2/kg^2 The density, ρ, of planet X is the same as earth, but the radius is 3 times that of earth

What is the mass and radius of the solar planets?

A table of mass and radius of solar planets Planet Mass (kg) Radius (km) Moon 7.35×1022 1738 Ganymede 1.48×1023 2631 Titan 1.35×1023 2575 Sun 1.99×1030 696000
